Researchers at the University of Cambridge, in collaboration with colleagues in Austria, report that tetrataenite, a “cosmic magnet” that takes millions of years to develop naturally in meteorites, can potentially be used instead of rare earth materials in magnets. Previously, attempts to make tetrataenite in the laboratory have depended on … [continued]
Renewable energy like solar and wind power can be made from free, abundant sources: sunlight and wind. We will never run out of either, and harnessing them to make clean electricity is not that difficult today because solar power and wind power have become highly efficient and cost-competitive at producing electricity. Furthermore, these efficiencies are set to increase over time because of the hard work of researchers and renewable energy business innovators. Energy storage is also growing and this technology can be used to fill in the gaps when there is no sunlight or wind, or during periods when there is less.
Finite fossil fuels powering transportation is problematic for a number of reasons, one of them being the non-renewable nature of crude oil. One of the solutions is, of course, the electric car ultimately recharged with electricity provided by wind, solar, or geothermal energy. But there’s another bottleneck – the rare … [continued]
